QR Codes, the two dimensional barcodes that originated in Japan, have been everywhere this past year and unless you have been living under a rock you are bound to have seen them and more than likely used them to receive data in some form. There’s been a lot of speculation about whether or not QR codes are all they’re cracked up to be, or just a flash in the pan. They have come a long way, and more accurate scanners have improved the situation. Personally, I’m a believer; I think they are a great advancement in data distribution. In grocery stores, the classic USB barcode, the QR code's one dimensional equivalent has a limited ability to hold information. The two-dimensional QR code ; enable much greater data storage than a bar code. As we’ve seen over the last year specifically, many marketers utilize QR codes in their campaign strategies and store information from something as simple as a web address redirect, to image file downloads in their codes. Though these have numerous benefits to businesses and webmasters, there have been security concerns that must be taken into account when creating and linking codes, but that's for another day.
